Application filed January 4, 1913.

To all whom it may concern Be it known that we, KARL VoLLnR, a subject of the German Emperor, residing at 12 Scharnhorststrasse, Dusseldorf, Germany, and EMIL MtiLLEn, a subject of the German Emperor, residing at 27 Jo-rdanstrasse, Dusseldorf, Germany, have invented certain new and useful Improvements in Means for Altering the Charges in Cartridges for Guns; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to means for removing and replacing the cartridge cases of projectiles in which it may be necessary to alter the charge, and forms an improve ment of the device described in patent specification British No. 9259 of 1911.

In the device shown in the said patent specification No. 9259 of 1911 a special cover is employed to hold the cartridge in the device for removing and replacing the cartridge case, which cover serves to preventthe cartridge from lifting, when the case is being replaced. Without the cover this could occur by the beveled edge of the cop per band striking against a projection of the device when the case was pressed home and causing the band to slide upward over the fixed ring, thus lifting the whole cartridge. The cover, which was necessary for this purpose, however, made the manipulation more complicated since two movements were required to close the cover and the rate of firing was decreased.

The present invention enables the cover to be dispensed with, without any danger of the cartridge lifting, when the case is pushed home. For this purpose the lower part of the support against which the beveled surface of the guiding band of the cartridge abuts is interrupted, so that the beveled edge of the copper band cannot strike against any projection at this part.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a longitudinal section of the device, Fig. 2 a cross section on line 22, Fig. 1, and Fig. 3 a horizontal longitudinal section.

Referring to the drawings, 9 indicates the support for the cartridge, the forward por- Specification of Letters Patent.

tion of which is generally U-shaped in cross section to partially embrace the projectile 7), and is provided with a groove or channel it formed in a peripheral flange or enlargement 6, which groove conforms to and is adapted to receive the band (Z of the projectile. Slidably mounted on the rear portion of the support 9 is the cart-ridge case engaging member 0 which is in all essentials similar to that shown in the British patent aforesaid, for which reason the actuating means for said member 0 is not shown.

In order to press the case a on to the proj ectile Z) in the manner described in the said British patent specification, the cartridge is placed with the copper band (Z in the groove 70. On drawing off the case a there is no danger of the cartridge tipping up, because in this direction the copper band engages with a rim normal to the cartridge. hen the case is being put on again, however, the beveled surface of the copper band d presses against correspondingly beveled rim of the groove h in the support. In order to prevent the cartridge from rising, the support against which the beveled surface abuts is cut away at the lower part f as shown in Fig. 2 so that there is no tendency for the inclined surface of the copper band to slide upward. The above described device also has the advantage that the groove for the copper band does not get dirty so easily because any sand particles or other grit entering it falls out at the bottom. This insures that the cartridge should always take up its correct position.

In order to prevent the copper band, by its wedge action, from deforming or forcing away the cartridge support the latter is considerably strengthened at the place where the groove for the copper band (l is, by means of reinforcing flange e, as seen in Figs. 2 and 3.

What we claim is:

1. A device for engaging and disengaging cartridge cases and projectiles comprising a support for the projectile having a groove to engage the projectile band said groove having its lower portion cut away to prevent contact with the beveled surface of said band.

2. A device for engaging and disengaging cartridge cases and projectiles comprising a U-shaped support for the projectile having a groove to engage the projectile band said groove having its lower portion cut away to prevent contact with the beveled surface of said band.

3. A device for engaging and disengaging cartridge cases and projectiles comprising a support for the projectile having a groove to engage the projectile band said groove having its lower portion cut away to pre vent contact with the beveled surface of said band, and a reinforcing flange on the exterior of said casing adjacent said groove.
